Solution Overview
Problem
Existing server designs face challenges with the upper cover being prone to torsional deformation and relative movement during transportation, leading to locking failure and increased risk of the upper cover falling off or failing to assemble properly, which complicates assembly and maintenance.
Innovation Solution
A connection module featuring a first connecting piece with a notch and limit end, and a second connecting piece with a telescopic positioning component and locking rivet, allowing for secure assembly and locking through flip-fit cooperation and telescopic positioning, preventing relative movement and deformation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the upper cover is fixed to the chassis using traditional clamping and locking methods, then the assembly can be disassembled without tools, but the upper cover becomes prone to torsional deformation and relative movement during transportation, causing locking failure
Solution Approach 1:
The connection structure is divided into multiple independent components: the upper cover, the chassis, the telescopic positioning component, and the limit piece. This segmentation allows each component to perform its specific function independently, with the telescopic component providing positioning and the limit piece preventing excessive movement, thereby maintaining reliability while preserving ease of assembly and disassembly.
Solution Approach 2:
The telescopic positioning component acts as an intermediary element between the upper cover and the chassis. It provides a flexible connection that can accommodate minor misalignments and movements during assembly, while the limit piece serves as another intermediary that prevents the upper cover from moving beyond safe limits. These intermediary components protect the main connection from direct stress and deformation.
2Reliability
If the upper cover is securely locked to prevent movement, then locking reliability improves, but the assembly complexity increases and disassembly becomes more difficult
Solution Approach 1:
The connection structure incorporates dynamic elements that allow it to adapt to assembly conditions. The telescopic positioning component can extend and retract to accommodate misalignments, and the limit piece can engage or disengage based on the assembly state. This dynamic behavior enables reliable locking without requiring complex fixed mechanisms, as the structure self-adjusts during assembly and operation.
Solution Approach 2:
The connection structure is designed to self-align and self-lock during assembly. The telescopic positioning component automatically positions the upper cover relative to the chassis, and the limit piece automatically engages to prevent excessive movement. This self-service capability reduces the need for complex alignment procedures and manual adjustment, simplifying the assembly process while maintaining reliability.
3Ease of manufacture
If traditional clamping and locking methods are used, then assembly is simple, but the upper cover is prone to torsional deformation and relative movement during transportation
Solution Approach 1:
The telescopic positioning component and limit piece are pre-installed on the chassis before the upper cover is attached. This preliminary action ensures that the positioning and limiting mechanisms are already in place to prevent torsional deformation and relative movement during assembly and transportation. The structure is prepared in advance to handle the stresses of assembly and operation, maintaining stability without complicating the actual assembly process.
4Ease of repair
If the upper cover is made removable for maintenance, then ease of repair improves, but the risk of falling off or locking failure increases
Solution Approach 1:
The connection structure is segmented into removable components (upper cover, telescopic positioning component, limit piece) that can be independently assembled and disassembled. This segmentation enables easy maintenance and repair by allowing the upper cover to be removed without affecting the chassis or other components. The modular design maintains connection reliability during normal operation while enabling easy access for maintenance when needed.
Solution Approach 2:
The telescopic positioning component and limit piece are designed with built-in protection mechanisms that prevent the upper cover from falling off or becoming misaligned during removal and reinstallation. The limit piece acts as a cushioning element that absorbs excess movement, and the telescopic component provides a buffer against misalignment. This beforehand cushioning ensures that the connection remains reliable even when the upper cover is frequently removed for maintenance.
